True RMS Digital Clamp Meter

The TA813 Series is a high-performance True RMS Digital Clamp Meter (Clamp Multimeter / Electrical Clamp Tester) designed for industrial electrical testing, equipment maintenance and field troubleshooting. Compliant with IEC61010 international electrical safety standards and rated CAT III 1000V, this series features a high-resolution VA color display, 6000/9999 counts measurement capability and automatic ranging for efficient and accurate electrical measurements in demanding working environments. The TA813 Series integrates multiple testing functions including AC current, DC current (TA813B+), AC/DC voltage, resistance, capacitance, inductance (TA813B+), frequency, duty cycle, temperature, continuity, diode testing, NCV non-contact voltage detection and live/neutral wire identification. It also provides advanced functions such as inrush current measurement, VFD voltage testing and high/low impedance voltage modes, making it ideal for troubleshooting variable frequency drives, servo systems, motor control circuits and industrial electrical equipment. The high impedance mode enables accurate standard voltage measurements, while the low impedance mode helps eliminate ghost voltage caused by capacitive coupling in control circuits, reducing measurement errors. The inrush current function captures the instantaneous startup current of motors, compressors and high-power equipment, helping technicians analyze overload conditions and startup faults. The dedicated VFD voltage measurement function improves testing accuracy on variable frequency drive output circuits. The TA813A+ is designed for general electrical inspection and maintenance applications, while the TA813B+ extends functionality with DC current measurement, inductance testing, relative value measurement and DC zero adjustment, making it suitable for DC control systems, renewable energy equipment, power supplies, servo drives and advanced troubleshooting tasks. With applications across industrial automation, electrical engineering, factory maintenance, HVAC servicing, renewable energy systems, machinery repair, building electrical maintenance, commercial facilities, technical training and laboratory testing, the TA813 Series is a versatile electrical diagnostic tool for electricians, maintenance engineers and professional technicians.
